SECONDARY BATTERY.

SPECIFICATION forming` part of Letters Patent No. 658,235, datedSeptember 18, 1900.l

Application led January 19, 1900. Serial No. 2,060. (No model.)

.To all whom it may concern:

Beit known that we, VIoToR'CHEvAL and JOSEPH LINDEMAN, subjects of theKing of Belgium, residing at Brussels, Belgium, have invented a new andImproved Accumulator- Battery, of which the following is aspecilication.

The main object of our invention is to so construct anaccumulator-battery as to secure a mechanically satisfactory dispositionof the active material and its complete utilization electrically.

In the accompanying drawings, Figure 1 is a vertical section of ourimproved battery, the section being taken upon line l l, Fig. 2. Fig. 2is a plan view, one-half being shown in section. Figs. 3 and 4 aredetached views of different forms of cartridge-like parts which may beemployed in the making up of one of our electrodes. Fig. 5 is asectional view of a modified form of battery.

One of our electrodes consists of a suitable number of cartridge-likedevices, (illustrated in Fig. 3,) and for convenience we will call themcartridges In the form of cartridge shown in this gure the activematerial z is placed in au envelop :c of insulating material perforatedwith a great number of small holes, the envelop being closed at itslower end and preferably of cylindrical or prismatic form. Pl unged intothe active material, and preferably in the axis of the cartridge, is aconducting-rod y, of carbon or of lead alloyed with antimony, providedat its upper end with a terminal w, provided with a thin lead rod o tobe connected with the connecting bars or plates u. The form of thesecartridges may be modified, as shown in Fig. 4. In this modilication theactive material z is placed between two envelops o: and to' ofinsulating material perforated with a large number of small hols andresting upon ani'm'perforate bottom. The electrolyte can enter theinterior of the inner envelop x. Into the mass of active material areplunged one or more conducting-rods of carbon or lead and antimony,which are connected to the terminal bars or plates u. The form ofcartridge just described is illustrated as employed in the battery Fig.2, while the form of cartridge described with reference to Fig. 3 isillus trated as employed in the battery shown in Y Fig. 5.

The other electrode is formedin the following manner: Each of thecartridges described above is surrounded with an outer envelop ofinsulating material a b c d, 85o., Figs. 1, 2, and 5. Such outerenvelops are perforated with a large number of small holes and aresecured at their ends to two plates E and F, provided for this purposewith large openings at suitable distances apart. These plates aresupported by four vertical walls A, B, C, and D of a box, Figs. l and 2,whose 'bottom G is at a certain distance from the plate F. In thisconstruction, Figs. 1 and 2,

the walls and bottom A, B, C, D, and G are imperforate. Between theseveral outer insulating envelops b c, dto., and the Walls A B C We packactive material q,'in which are placed conducting-rods t, of the samematerial as the other electrode. These'conducting-rods are soldered toconnecting terminal rods or plates s. The Walls A B C and bottom Gcontain the electrolyte H, whichbeing introduced into the spaces betweenthe insulating envelops ct b c, &c., and the cartridges containedtherein comes into contact at the same time with the two sets ofelectrodes.

Instead of constructing the battery so that the walls A B C D and bottomG contain the electrolytethe electrodesconstructed as described may beplaced in an external receptacle o" to receive the electrolyte, asillustrated in Fig. 5.

We claim as our invention- In an accumulator-battery, an electrodeconsisting of a series of cartridges withfperforated envelops`containing active material, in combination with another'electrodeconsisting of other perforated envelops surrounding the said cartridges,with intervening spaces for the electrolyte, active material packedaround said outer envelops and between them and the walls of thebattery, and conducting-rods in such active material, substantially asdescribed.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
